left and right sections-28 and 28 ,and a door section 29. The sections 28 and 28 lie 1n one plane,and together have. a circular Inargin, which isreceived in a groove 30 (see "Fig.{r5l) presentedby a projection 3l, herein forinedv as an integral partl of, the' circumfen.y ential wall 22 ofthe smoke box casting.

, Referring now to Fig. 3,

V v n e thesparlrnetting* section-S28 and .28 arejoined togetherby bar; 34which presents oppositelydispo'sed .j grooves 35 and v35', in whichadjacent: edges of thek sections 28 and 28" `are received. :Thief-f lprovides a joint which prevents ythe passage f of sparks, and which `nevertheless perrnitsff the parts to be assembled anddisrnountedi 'v with ease, vas the bar can=be `removed.'by l simply sliding it lengthwise/outlet its place, 1

when v the 'door section 29V is absent. On the su Vother hand, when Ithegdoorv section is in', place,,

it locks the bar in place.: In thefpresentex# ample, the bar `is 4further,securediby the usedrv f vof Cotter-pins 36,-. which extend ethroughf;l and thence through -8'5y interstices'xotthe netting section-28.. j VV; fj

The door section' is-Inounted' i11a"son1e=';. what 'similar,nianner(see Fig. 4),-it-,beingfw J opposite wallsof .the bar,

received ina frame composedof bars {s u'ch as the bar 37;, havinga groove38,which1ref ,of the door frame presentsa recess 40 for k9o nceives the ad]acent edge of thenettingsectienv 28. The bars; lmay be secured to the netting.l i sections by welding" theinrtogether, as indi-.i cated kat 89.` Each bar whichv forms. a part f the rmarginal v,portion of 'thedoor, whichkv 'f may be` secured in place by appropriate `f'asm;

' teningineans, such as pins 4l: and'keys 42. f

Thespark netting` structurefas thus atar y describedhas its marginal portion through-` 'portion 27 of the deflector sagging orl warp,

Y ing, due to its 'exposure tothe hot gases, the

spark` netting may bel used as ,a meansl of.;

To this end, inv thepresent"exaniple'the upper` Y corners ofthe spark nettingl sections 28-andf` 28jare secured-inthe'groove 3,0V of thesepro jection 3l, by pins, such as the -pin 4:3 (see Fig. 5), held in place by the cotter pin 4.4i, while the lower corners are held in place in the groove 32 (see F ig. l)V oi a projection 33 by similar pins 45.

Thus it is evident that there is no possibility of warping1 oit the parts, which might permit sparks to pass through thejoints, while at the same time, the simplicity of the arrangement is such that the door section of the spark netting can be removed `and replaced with great facility, andiii desirable, thelremaining sections'can be removed and replacedwith equal ease.

This application isa division ot my pending application for locomotive smoke-box structures, Ser. No. 34,405, tiled J une 2 1925.
